SYRINGE Filed May 29, 1928 i A a Patented July 1, 30 2 Louis F. NovAK, OF JERSEY CITY, 'ivnw JERSEY FSYRINGEY 7 Application filed ma 29,

My invention relates toimprovements in syringes, particularly in vaginal. syringes, and the primary object ofmy invention is the provisionof a syringe of'this character embodying means to provide a whirling cleansing spray. forward, and including a novel air duct arrangement to permit the drawing of air into the vaginalcanal as the syringe isbeingf withdrawn in order 'rio to create asuctional effectand to eliminate the formation .of a vacuum which 1s harm'- ful to the inner organs Y pended claims.

In the modified orm of my invention illustrated in Figure 6, the air duct is shortened and straight, as shown, or can be omitted and replaced by a stud or screw 27 or the like having a central bore and im- Vidin an air duct, and supporting the discs and t e tip of the nozzle, otherwise the construction is the same as described above with res ectlto the preferred form.

t will be understood that I have shown "as examples of the many ways in which my syringe ma be practically constructed the preferred orms thereof only, and that I may make such changes as come within the scope of the appended claims in the general arrangement and in the construction of the minor details of my invention without de parture from the spirit of my invention and the rinciple involved. I i

aving thus described my invention, what I claim asnew, and desire to secure by Lettens Patent is:

1. In a vaginal syringe, the combination of V a main tube, having a collapsible bulb at one ofits ends; and a nozzle at the opposite end thereof, with an air vent tube within said 7 main tube carrying the nozzle at one end and communicating with the atmosphere at its 3. Avvaginal other end a disc on said air vent tube at a distance from the mouth of said main tube,

of, a short straight air vent tube extending into said main tube carrying said nozzle, a slotted disc on said vent tube, a rotary disc on said vent tube, cooperating with said slotted disc to impart to the cleaning fluid issuing through said nozzle, a whirling action upon the compression of said bulb, and a means for leadin air into the vaginal canal during the withd rawal of the syringe from the vagina.

4. In avaginalsyrimge the combination of a main tube having a passageway therethrough open at opposite ends of the tube, a

collapsible bulb attached at one end to said tube, a nozzle supporter at the opposite end of the said tube, a short air vent tube extend ing longitudinally in the passageway of said main tube and having air inlet at the rear end thereof, said air vent tube having an exit at the front end thereof at the extreme top of said nozzle, said air Vent tube allowing the introduction of air upon the withdrawal of the syringe from the vagina, and a means to impart to the cleaning. fluid a whirling motionduring its issue from said nozzle upon the compIression of said bulb.

said disc havin a plurality of radial openings, another isc rotatably held on said air vent tube in front of said first named disc, said second discprovided with openings communicatin with the openings in said first named isc, turbine buckets on said second disc adapted tobe rotated by the cleansing fluidpressed by said bulb through the main tube and issuing from said nozzle to to saidfluid a whirling cleansing motion to reach all parts of the vagina, and

means allowing the introduction of air into the vagina during the withdrawal of the syr nge preventing the formation of a vacuum within the organ.

2. A va a1 syringe comprising a collapsible bu b, a curved main tube connected bulb, a seat formed at the outer end of said main tube, a means for imparting to the fluid a forwardly directed whirling, a
